“…The high values of photosynthetic pigments was recorded at 10 ppm selenium, being 54 , 55 , 54.3 and 22.6 % over the control for Chl a , Chl b, total Chl and carotenoids in the first season, respectively and it was 50.8 , 66.6 , 50.3 and 23,8 % more than the control in the second one. These results are in accordance with those reported by Padmaja et al (1989). It was found that ,higher concentration of Se decreased chlorophyll content in mungbean plants.…”

T HIS WORK was conducted during the two successive winter seasons of 2014/ 2015 and 2015 / 2016 at the Agricultural Experiments and Researches Station (Ghazala Farm), Faculty of Agriculture , Zagazig University , Sharkia Governorate, Egypt, to study the effect of foliar spray with selenium at concentrations of 0, 2.5 , 5 , 10 , 15 and 20 ppm on growth, chemical composition , yield as well as anatomy of stem and leaves of faba bean cv. Giza 716. The experimental results showed that foliar application with 20 ppm selenium showed no effect on vegetative growth , yield components ,seed quality, photosynthetic pigments (chl a , chl b, total chl and carotenoids) concentration, carbohydrates fractions , minerals and crude protein percentage. Foliar application with 10 ppm selenium significant improvement effects on vegetative growth , yield, seed quality, photosynthetic pigments, carbohydrates fractions, minerals and crude protein percentage of faba bean cv. Giza 716. Foliar application with 10 ppm selenium induced favorable enhancement in anatomical feature of stem and leaves. Exogenous application of selenium also induced prominent increase in diameter of stem, thickness of cortex, number of cortical layers, average length and width of vascular bundle, average vessels number per vascular bundle and average diameter of vessel . Likewise, increased thickness of both midvein and lamina, increased thickness of mesophyll size of midvein bundle, length and width of midvein bundle and vessel diameter were increased as a result of spraying selenium.

“…It is believed also that Se induces toxicity in plants by interfering with chlorophyll synthesis (Padmaja et al 1989 ) as well as with nitrate assimilation (Aslam et al 1990 ). There is also evidence that Se can interfere with production of glutathione, and thus reduce a plant's defense against hydroxyl radicals and oxidative stress (Bosma et al 1991 ).…”

“…The strong inhibitory effect of Se(IV) on photosynthetic pigments production was also observed in our tests when Chla, Chlb and Car production was reduced on 46, 23, and 8%, respectively. Se induces chlorosis, possibly through an adverse effect on the production of porphobilinogen synthetase, an enzyme required for chlorophyll biosynthesis (Padmaja et al 1989).…”

The priority of this study was to investigate how selenium influences toxicity of Cd, Zn, Cu and Pb when the metals appear in the hydroponic solution in pairs. As a model subject mustard seedlings (Sinapis alba L.) were used. Except phytotoxicity of individual metals and Se-metal combinations determined through photosynthetic pigments content (chlorophyll a, b, total carotenoids) also metal accumulation in the roots and shoots was determined by the AAS method. Se in all metal combinations reduced the unfavourable effect of other metals tested for chlorophylls content, however, for carotenoids primarily the opposite effect occurred. For metal accumulation in the roots and shoots it was confirmed that Se stimulated only Cd (about 24%) and slightly Cu (about 9%) accumulation in the roots, while in the shoots there was inhibited accumulation of all metals tested. The strongest inhibition was observed in Pb accumulation (84.9%). This fact indicates that Se generates some barriers for metal transfer from the roots to the underground plant parts. In contrast, Cu, Zn, Pb and Cd increased Se accumulation in the roots in the range of 4 (in combination with Cu) to 68% (in combination with Cd) and in the shoots in the range of 11 (in combination with Pb and Zn) to 44% (in combination with Cd). In the shoots only Cu inhibited Se accumulation (about 67%).
